1SDA072504R1 ABB E4.2S 3200 Ekip Touch LI 3p WMP Air Circuit Breaker

Why Choose the ABB E4.2S 3200 Ekip Touch LI 3p WMP Air Circuit Breaker?

The ABB E4.2S 3200 Ekip Touch LI 3p WMP, order code 1SDA072504R1, is a high-performance three-pole air circuit breaker (ACB) moving part from the ABB SACE Emax 2 range, engineered for protection and switching in demanding low-voltage electrical distribution systems. Combining the E4.2S frame with a 3200 A rated uninterrupted current and ABB's Ekip Touch LI solid-state electronic trip unit, it provides reliable overload and instantaneous short-circuit protection for high-current industrial, commercial and infrastructure power networks.

This breaker uses a withdrawable construction for integration with a compatible Emax 2 fixed part, supporting efficient inspection, servicing and replacement within switchboard installations. Its Ekip Touch LI electronic release provides long-time overload and instantaneous short-circuit protection, while the Touch interface provides an accessible platform for configuring and supervising the protection functions.

The E4.2S 3200 delivers an ultimate short-circuit breaking capacity of 85 kA at 400/415 V AC and 66 kA at 690 V AC. Its combination of a 3200 A current rating, three-pole configuration, high short-circuit performance, four auxiliary contacts and withdrawable moving-part construction makes the 1SDA072504R1 particularly suitable for main distribution, incomer and high-current feeder applications.

Advanced LI Protection for High-Current Power Distribution

The ABB SACE Emax 2 E4.2S platform is engineered for high-current low-voltage networks where dependable fault interruption and electrical system protection are essential. The 1SDA072504R1 combines a substantial 3200 A rated uninterrupted current with 85 kA Icu at 400/415 V AC and 66 kA Icu at 690 V AC, providing robust protection for main switchboards, transformer-fed systems and other high-capacity distribution networks.

The Ekip Touch LI electronic trip unit provides long-time overload protection and instantaneous short-circuit protection. Its overload release can be adjusted from 1280–3200 A, allowing the breaker to be configured for the protected circuit, while instantaneous protection provides rapid interruption of severe short-circuit faults. As an LI configuration, this breaker does not incorporate the dedicated short-time or ground-fault functions associated with LSI and LSIG releases.

Typical Applications

• High-current low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Large manufacturing and process plants.
• Commercial and infrastructure electrical distribution.
• Data centres and critical power installations.
• Utility and infrastructure switchgear.
• Transformer-fed distribution systems.
• High-current incomer and feeder protection.
